readilyfilling and emptying a nest of battery cells, to pe1rnit,the ready removal and replacement of the several cells, and to prevent leakage of current or its passage from one cell to the other, either through the supply-comduit or the battery fluid contained therein. These objects are attained by providing a suitable casing for holding the cells in their proper relation, employing a peculiar supplying and discharge system having improved couplings whereby the several cells comprises a nest .of cells 1, each having the ducts 2 and 2 communicating therewith and with the branch conduits 3, connected with the main conduits 4, the whole being carried by a tight casing 5, as shown in Fig. 1,

or in an open casing 6, as shown in Fig. 2.

Each duct 2 is provided with a bend 2" and an arm 2', having apertures 2 therein,

and each cup is provided with a base exten.,

sion 7, having an aperture 7, through which the arm2 passes, and an aperture 7 wlth which the aperture 2 communicates.

.The base extensions provide the passages 7,

through which free circulation between the bottoms of the several compartments is established.

In-the form of coupling shown in Figs. 8 to 13, inclusive, the union 9, suitably made of soft rubber, has the tapered socket 3*. for receiving the tapered end of the conduit 3 and the tapered sockets 2 for receiving the tapered ends of the ducts, as 2, the several sockets being connected by the passages 2 and 3 In the form ofcoupling-shown in Figs. 14 to 16, inclusive, the union 10 has the tapered sockets 2 and 3*, connected by the passage 3*, the socket 2 receivingthe tapered hollow stem 2 by which the ducts, as 2, are connected, and the socket 3 receiving the tapered end of the conduit 3.

In the form of coupling shown in Figs. 17 to 19, inclusive, the union 11 has the tapered sockets 2 and 3*, connected by the passage 2, the-sockets 2 receiving the-tapered ends of the ducts, as 2, and the socket 3 receiving the tapered end of the conduit 3, which lies between the ducts 2 and the cells 1.

The several cells may be provided with the as-ve'nts 12 and the air-ports 13, controlled y avalve comprising the angularly-arranged wings 14 and 15 rocking on thepivot 16 andadapted for closing the respective openings 12 and 13. The valve is weighted, so that the vent is normally maintained opened to permit escape of gas, and the port is normally maintained closed to cut off communication from the cell therethrough. When a blowing device is connected with the air-port and air forced therethroughto discharge the fluid from the cells through the conduits, the rock ls f ing of the valve effected thereby closesthe vent. p

Inusing-the tight'casing5v the cells may be I made to communicate freely therewith, while the casing-lid 5? may be providedwith the gas-vent12a'nd the air-p0r t.13, controlled by the valve 14 15.

Having described my invention, I claim 1. A battery comprising a plurality of cells, a duct extending into the interior of each of said cells, a conduit communicating with a plurality of said ducts, and means for. connecting said conduit to said ducts, said connection permitting the removal of said cells and ducts without moving said conduit, substantially as specified.

2. A battery comprising a plurality of cells, a duct extending into the interior of each of said cells, a main conduit, a plurality of branch conduits each communicating with I said main conduit and with a plurality of said ducts; and means for removing and replacing the respective cells and their ducts independently of the remaining cells and their connections, substantially as specified.

3. A battery having an inclosed cell, a vent leading therefrom, a port leading thereto, and a pivoted valve which normally closes said .port and opens said vent, said valve be ing moved by pressure to open said port and 7 simultaneously close said vent, substantially as specified.
